I've been an android user since 1.5. I've run every major revision along the line (and most minor revisions, too). There have been some great milestones, like 2.0 and 2.3. I admit to having some major aesthetic reservations with Cupcake and Donut (grey, grey, grey, and that app drawer button!
) but even though I think Android has gotten vastly more clean and attractive to look at, it's the little things I really love.
I'm running 4.1.1 on my HTC Ville, and there are tons of little usability tweaks I just love. I had been running 2.3.6 on my Vision before (with some backported Jellybean goodies, but nothing major) and while it was quite functional, there were a lot of little things I wished I could tweak, or access more easily, or just have happen automatically or more effectively.
JB adds so much goodness.
My favorite thing by far is the new notification system. Notifications can have multiple sizes and added functions (like buttons, or images). There's also improved priority management, and the ability for the user to completely disable all notifications from any app, which is AMAZING AS HELL. Goodbye, GameLoft Live notifications!
The second best thing? Project Butter. The chief bragging point iOS owners had over Android is gone. JellyBean is smooth as silk on teflon coated in 0-20 synthetic. Not just system stuff, either. Transitions from application to application are quick, smooth, and responsive. Screen rotation animations are quick and natural and smooth. Everything is fast and stutter-free.
Also on the list of awesome:
Google Now. A genuinely useful combination of voice commands, personalized search, and customized dynamic information feed. The voice search is impressive, and the way it returns results feels very natural. The personalization makes it even more effective (I found nicoclub.com with a single voice search, just by saying the url...but it IS one of my bookmarks).
Offline voice input. Unlike iOS and Android 4.0 and earlier, Jellybean lets users type or command with their voice without a data connection. My week in Anaheim (a place where T-mobile high speed data coverage is spottier than the pope. Or holier. One of those.) showed me just how useful that was. I could still dial and text and search for media, apps, and functions without worrying about data coverage. And as a bonus, I wasn't wasting bandwidth.
I <3 Android.
